Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Neuro-oncology

Background:

  • Gliomas are aggressive brain tumors with challenging-to-define boundaries in clinical practice.
  • Fluid-attenuated inversion recovery (FLAIR) Magnetic Resonance Imaging (MRI) aids in visualizing tumor infiltration.

Purpose of the Study:

  • To propose DeepSeg, a generic deep learning architecture for automated brain lesion detection and segmentation.
  • To utilize FLAIR MRI data for enhanced tumor boundary identification.

Main Methods:

  • Developed a modular decoupling framework (DeepSeg) with encoder-decoder architecture.
  • Employed Convolutional Neural Networks (CNNs) including ResNet, DenseNet, and NASNet within a modified U-Net.
  • Tested on the BraTS 2019 challenge dataset with 336 training and 125 validation cases.

Main Results:

  • Achieved Dice scores between 0.81 and 0.84.
  • Obtained Hausdorff distance scores ranging from 9.8 to 19.7.
  • Demonstrated successful online testing and evaluation of the deep learning models.

Conclusions:

  • Confirmed the feasibility and comparative performance of DeepSeg for automated brain tumor segmentation.
  • Highlighted the potential of various deep learning models within the DeepSeg framework.
  • The DeepSeg framework is open-source and publicly available for research and clinical use.
